2) The way the coordinates show the given scale factor is that the ratio of both x and y coordinates to the mapped coordinate before dilation are all equal.

3) The coordinates after dilation are: (5.4, 27)

How to use scale factor dilation?

2) The coordinates transformed points after dilation are completed as:

B(2, 4) → B'(3, 6)

K(4, -4) → K'(6, -6)

N(-6, 0) →N'(-9, 0)

The scale factor is same because using the ratio of the x coordinates gives:

3/2 = 1.5

6/4 = 1.5

-9/-6 = 1.5

3) The point W of the vertex of the polygon has coordinates as (2, 10)

Thus, if dilated by a scale factor of 2.7, we have the new coordinates as:

(2*2.7, 10*2.7) = (5.4, 27)

if a small cup is 10 oz and cost 2.69 what is the cost per ounces

Answers

Answer:

The cost per ounce of the small cup is $0.269

Step-by-step explanation:

To find the cost per ounce, we can divide the cost of the cup by the number of ounces it holds.

Cost per ounce = Cost of the cup ÷ Number of ounces in the cup

Cost of the cup = $2.69

Number of ounces in the cup = 10 oz

So,

Cost per ounce = $2.69 ÷ 10 oz

Cost per ounce = $0.269 per oz (rounded to the nearest thousandth)

Therefore, the cost per ounce of the small cup is $0.269.

The distribution of the numbers of siblings is best described as skewed to the right so, the median will be a more appropriate measure of the center than the mean

What is positively skewed data?

If data is positively skewed - which means that the tail of the distribution leans towards higher values - the median will often be a superior indicator for ascertaining the center than the mean.

This advantage can be attributed to the fact that the median outright ignores extreme values, unlike the median which may become influenced by them and thus pulled towards the extremes of the overall set. Since it is simply the middle value obtained upon sorting the data, its sensitivity to conspicuous outliers is more limited.

Find the surface area of a right square pyramid if the area of the base is 169 cm² and the slant height of the pyramid is 13 cm.​

Answers

The surface area of a right square pyramid if the area of the base is 169 cm² and the slant height of the pyramid is 13 cm is 507 cm².

Calculating the surface area of square pyramid

We know that the area of the square base is 169 cm², so we can solve for the length of one side.

To find the length, we use the formula for the area of a square:

Area = length x length

169 = length²

Taking the square root of both sides, we get:

length = √169

        = 13 cm

Now we can use the formula for the surface area of a square pyramid:

Surface area = area of base + (1/2)perimeter of base x slant height

The perimeter of the base is 4 times the length of one side, so it is:

perimeter of base = 4 x length = 4 x 13 cm = 52 cm

Plugging in the values we have:

Surface area = 169 cm² + (1/2)(52 cm)(13 cm)

Surface area = 169 cm² + 338 cm²

Surface area = 507 cm²

Therefore, the surface area of the right square pyramid is 507 cm².

A triangle with an area of 0.45m squared and a perimeter of about 325cm?
pls help meee

Answers

Answer:To solve this problem, we need to use the formulas for the area and perimeter of a triangle.

Let's start by using the formula for the area of a triangle:

Area = (base x height) / 2

where base and height are the length and height of the triangle's base, respectively.

Let's assume that the base of the triangle is x meters, and the height is y meters. Then we have:

Area = (x*y)/2 = 0.45 m²

Solving for y, we get:

y = (2*0.45)/x

y = 0.9/x

Now, let's use the formula for the perimeter of a triangle:

Perimeter = a + b + c

where a, b, and c are the lengths of the three sides of the triangle.

Since we know that the perimeter is about 325 cm, we can assume that the three sides are close to each other in length. Let's assume that each side has a length of 325/3 = 108.33 cm.

Converting to meters, we get:

a = b = c = 108.33/100 = 1.0833 m

Now, we can use the formula for the area of a triangle again to solve for x:

Area = (base x height) / 2

0.45 = (x * 0.9/x) / 2

0.9 = x²

x = √0.9 = 0.9487 m

Therefore, the base of the triangle is approximately 0.9487 meters, and the height is approximately 0.9/0.9487 = 0.9487 meters.

So the triangle has sides of length 1.0833 meters and a base of length 0.9487 meters, which gives us a perimeter of approximately 3.215 meters (rounded to three decimal places).

if there are 18 triangles in a polygon how many sides has the polygon​

Answers

The number of sides of a polygon that has 18 triangles would be 20 sides.

How to find the number of sides ?

To determine the number of sides in a polygon consisting of 18 triangles, we can calculate the sum of the interior angles. Each triangle has total interior angle sum of 180 degrees, and since there are 18 triangles, the sum of those angles would be 18 multiplied by 180, which comes to 3, 240 degrees.

Applying the given formula for calculating the interior angles of a polygon, we obtain that (n - 2) multiplied by 180 stands for the sum of all angles within it, with n being the number of sides.

Hence, rearranging the equation gives n :

n = (sum of interior angles ÷ 180) + 2

n = (3240 ÷ 180) + 2 = 20

There must be precisely 20 sides in that particular polygon.

Prove that sinθ cosθ = cotθ is not a trigonometric identity by producing a counterexample.

Answers

Answer:

cmon man

Step-by-step explanation:

We want to show that sinθ cosθ = cotθ is not true for all values of θ. To do this, we just need to find one counterexample, i.e., one value of θ for which the equation is not true.

Recall that cotθ = cosθ/sinθ. So, the equation sinθ cosθ = cotθ can be rewritten as sinθ cosθ = cosθ/sinθ.

Multiplying both sides by sinθ, we get:

sin^2θ cosθ = cosθ

Dividing both sides by cosθ, we get:

sin^2θ = 1

Taking the square root of both sides, we get:

sinθ = ±1

So, we need to find a value of θ such that sinθ is equal to ±1. This occurs when θ = π/2 + kπ, where k is an integer.

Now, let's check whether sinθ cosθ = cotθ is true for this value of θ. We have:

sin(π/2 + kπ) = ±1

cos(π/2 + kπ) = 0

cot(π/2 + kπ) = undefined (since cos(π/2 + kπ) = 0)

Therefore, sinθ cosθ = cotθ is not true for θ = π/2 + kπ, and we have found a counterexample. This shows that sinθ cosθ = cotθ is not a trigonometric identity.

How to find the true statements

To find the true statements about the graph that represents y = -2x(x - 11), we need to analyze the equation and its properties.

x-intercepts by setting y = 0 and solving for x:

form the equation we have y = -2x(x - 11)

0 = -2x(x - 11)

0 = x(x - 11)

x = 0

x = 11

The x-intercepts are at (0,0) and (11,0).

Now let's find the vertex of the parabola. The vertex is located at the x-coordinate x = -b / 2a,

y = -2x^2 + 22x

given that

a = -2,

b = 22

x coordinate of the vertex is found by

How to solve

a)

Note that the probability of x successes out of n trials is

P(n, x) = nCx p^x (1 - p)^(n - x)

where

n = number of trials = 12

p = the probability of a success = 0.33

x = the number of successes = 3

Thus, the probability is

P ( 3 ) = 0.21509867 [answer]

Note that P(at least x) = 1 - P(at most x - 1).

Using a cumulative binomial distribution table or technology, matching

n = number of trials = 12

p = the probability of a success = 0.33

x = our critical value of successes = 4

Then the cumulative probability of P(at most x - 1) from a table/technology is

P(at most 3 ) = 0.402659566

Thus, the probability of at least 4 successes is

P(at least 4 ) = 0.597340434 [answer]

Citywide Delivery Inc. budgets $190 per month for telephone costs, which include the 3% federal excise tax. Citywide uses approximately 4,000 minutes per month, so the company signed up for the $96.00 plan. What is the maximum number of lines Citywide can sign up for and stay within their budget? Use the figure below:

Answers

Since we can't have a fractional number of lines, Citywide can sign up for a maximum of 1 line and still stay within their budget.

Let's start by calculating the total amount Citywide pays for their telephone costs without the federal excise tax. We can do this by subtracting the 3% tax from the total budget:

$190 / 1.03 = $184.47

The $96 budget plan includes 4,000 minutes, which means that each minute costs:

$96 / 4,000 = $0.024

If Citywide wants to stay within their budget, they need to make sure that the total cost of the lines they sign up for plus the federal excise tax is less than or equal to $190.

Let's represent the number of lines Citywide signs up for as "n". The total cost of the lines plus tax can then be represented as:

n * $96 * 1.03

Setting this expression less than or equal to $190, we get:

n * $96 * 1.03 <= $190

Simplifying, we get:

n <= $190 / ($96 * 1.03)

n <= 1.945

Thus, Citywide can sign up for a maximum of 1 line and still stay within their budget.

Using the given data, a logarithmic regression equation of the form Bacteria = 447.91 * ln(12) - 1733.1 was found to model the relationship between time and bacteria population. So, the population of bacteria is about 44.1 at 12 hours.

Based on the provided data, we can use a logarithmic regression to model the relationship between time and bacteria population. Here's how to do it using Microsoft Excel

Enter the data into two columns one for time and one for bacteria population. Create a scatter plot of the data. Right-click on one of the data points in the plot and select "Add Trendline."

In the Trendline options, choose "Logarithmic" as the type of trendline. Check the box for "Display Equation on Chart" to show the equation for the trendline.

Bacteria = 447.91 * ln(Time) - 1733.1

This equation represents a logarithmic regression of the bacteria population over time.

To use this equation to predict the bacteria population at a specific time, substitute the time value into the equation and solve for the bacteria population. For example, if we want to predict the bacteria population at 12 hours, we can substitute 12 into the equation

Bacteria = 447.91 * ln(12) - 1733.1

We can factor each of the given terms so that 4x^2 shows up

8x^5 = 4x^2*2x^3

12x^3 = 4x^2*3x

20x^2 = 4x^2*5

This shows how 4x^2 is the GCF of 8x^5, 12x^3, and 20x^2

-----------------

Here's how to find the GCF of terms involving variables.

First, find the GCF of the coefficients 8, 12 and 20.

List the prime factorizations

8 = 2*2*212 = 2*2*320 = 2*2*5

Then circle "2*2" since it is found in all three factorizations. Do not circle 3 because it's not found in 8 or 20. Do not circle 5 since it's not found in 8 or 12.

Therefore, the GCF of {8,12,20} is 2*2 = 4.

As for the variable terms, we look for the smallest exponent.

The exponents for x^5, x^3, x^2 are 5,3,2 in that order. The smallest exponent is 2, so x^2 is part of the GCF.

What is the domain of the function y=tan (x/8)

Answers

The domain can be written as follows:

R - {x = n*12pi or m*4pi | n, m ∈ Z}

where pi = 3.14 and R is the set of real numbers.

What is the domain of the function?

Here we want to find the domain of the function:

y = tan(x/8)

The tangent is the quotient between the cosine and the sine, then we will get:

sin(x/8)/cos(x/8)

The problems of the tangent are all the values that make the denominator equal to zero, then we need to remove these.

The zeros are:

cos(x/8) = 0

We know that cos(pi/2) = cos(3pi/2)  = 0

Then:

x/8 = pi/2

x = 4pi

x/8 = 3pi/2

x = 12pi

So the domain is the set of all real numbers except the ones in the next set:

{x = n*12pi or m*4pi | n, m ∈ Z}

Where Z is the set of integers.

Part 1
A certain flight arrives on time percent of the time. Suppose flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that
​(a) exactly flights are on time.
​(b) at least flights are on time.
​(c) fewer than flights are on time.
​(d) between and ​, inclusive are on time.

Answers

The probability that exactly 128 flights are on time is 0.0950.

The probability that at least 128 flights are on time is 0.5079.

The probability that fewer than 124 flights are on time is 0.2147.

How to calculate the probability

It should be noted that exactly 128 means P(X=128) = P(127.5 < X < 128.5) (By using continues correlation )

At X = 127.5

Z =(127.5-127.6) / 3.91305 = -0.02

At X = 128.5

Z =(128.5-127.6) / 3.91305 = 0.22

P(127.5 < X < 128.5) = P(-0.02 < Z < 0.22)

P(127.5 < X < 128.5) = P(Z < 0.22) - P(Z < -0.02)

P(127.5 < X < 128.5) =0.58706 - 0.49202

P(127.5 < X < 128.5) =0.0950

(b) at least 128 flights are on time.

P(X > 128) = P(X > 127.5) (by using continues correction)

P(X > 127.5) = P(Z > (127.5-127.6)/3.91305)

P(X > 127.5) = P( Z > -0.02)

P(X > 127.5) = 1- P( Z< -0.02)

P(X > 127.5) = 1- 0.49202

P(X > 127.5) = 0.5079

(c) fewer than 124 flights are on time.

P(X < 124 ) =P(X<124.5) (by using continouse correction)

P(X<124.5) = P(Z < (124.5-127.6)/3.91305)

P(X<124.5) = P(Z < -0.79)

P(X<124.5) = 0.2147

The value of the expression 0.738 divided by 8.2 is between which two numbers?
A) 0.06 and 0.08 B) 0.08 and 0.1 C) 0.1 and 0.5 D) 0.7 and 1

Answers

To estimate the value of 0.738 divided by 8.2, we can round both numbers to one decimal place:

0.738 ≈ 0.7
8.2 ≈ 8.0

Then we can divide 0.7 by 8.0:

0.7 / 8.0 ≈ 0.0875

So the value of the expression is approximately 0.0875. This is between the values in answer choice B, 0.08 and 0.1. Therefore, the answer is B) 0.08 and 0.1.

Answer:

B) 0.08 and 0.1

The answer was 0.09, which is between 0.08 and 0.1

Larry Sergio Katrina Jim Ian Tyrone Maria and Sarah are invited to a dinner party.

Answers

The number of ways they can is 40,320.

The number of ways Larry can arrive first and Sarah can arrive last is 720.

The probability that Larry arrives first and Sarah arrives last is 0.01786.

We have,

a)

Since each person can arrive at any time, the number of ways they can arrive is equal to the number of permutations of 8 people, which is:

= 8!

= 40,320

b)

To calculate the number of ways Larry can arrive first and Sarah can arrive last, we can fix their positions and then permute the remaining 6 people in the middle.

= 1 x 6! x 1

= 720

c)

To find the probability that Larry arrives first and Sarah arrives last, we need to divide the number of ways they can arrive in the desired order (720) by the total number of ways they can arrive (40,320):

= P(Larry first and Sarah last)

= 720 / 40,320

= 0.01786

So the probability is approximately 0.01786, or about 1.8%.

Thus,

The number of ways they can is 40,320.

The number of ways Larry can arrive first and Sarah can arrive last is 720.

The probability that Larry arrives first and Sarah arrives last is 0.01786.
